Questions & Answers

As answered by people managing Zen Browser and HTMLCSS to Image API.

Which are the primary technologies used for building your product?

HTMLCSS to Image API's answer:

HCTI is built with C# and .NET, using ASP.NET Core for the API and Chromium with PuppeteerSharp for browser rendering.

The rendering infrastructure combines stateful and serverless compute for speed and scalability. Cloudflare Workers sit in front of every API request, and Cloudflare provides our CDN.

The visual template editor is built with Blazor WebAssembly.

For developers integrating with HCTI, the interface is a REST API with JSON requests. Call it from any language that supports HTTP, or use one of our handwritten client libraries, built for performance. Most have zero dependencies.

What makes your product unique?

HTMLCSS to Image API's answer:

You design with HTML and CSS. HCTI takes care of rendering it.

Use the layout techniques, fonts, and styles you already know to generate images programmatically. A social card can use the same styling as your website. A report can pull in live application data.

Send raw HTML and CSS, capture a URL, or create a reusable template and pass in new values. The visual template editor also lets teammates work on designs without editing your application code. Images, PDFs, screenshots, and template-based graphics all run through the same API.

We've spent years working on the infrastructure side, too. Before starting HCTI, we worked on scaling very large online services at large companies. That experience shaped how we built HCTI: speed and scalability have been priorities from the start, alongside the day-to-day experience of developers using it.

We put that same attention into clear documentation, practical code examples, and an API that's straightforward to integrate. Getting your first image should be easy. Growing that integration into a production workload should be, too.

How would you describe the primary audience of your product?

HTMLCSS to Image API's answer:

HCTI is built for developers who need to generate images and PDFs as part of their product. Think social previews for every page, personalized graphics for every customer, or reports generated directly from application data.

It's a natural fit for teams that already work with HTML and CSS. You can bring your existing designs and make image generation part of your codebase without maintaining browser infrastructure.

Marketing and operations teams use HCTI, too. Reusable templates and integrations with Zapier, Make, and n8n let them generate graphics from new content, spreadsheet rows, or workflow events without asking a developer for every variation.

From a solo developer shipping a feature to a team generating images at scale, the common need is the same: turn content and data into finished visuals automatically.

    Hmm, I don't know - I've been using Zen [1] primarily the last couple of hours and it seems to have come a long way since I last tried it. Thanks for sharing carbonyl & brownsh, they seem quite cool. Just not sure they'd be the perfect... - Source: Hacker News / 1 day ago

    There is also Zen which is quite active: https://zen-browser.app/. - Source: Hacker News / 7 days ago
  • I Switched to Brave Browser
    > I LOVED Arc. I assume you've heard of it, but just in case you haven't: you should try Zen! It's basically Arc, but based on Firefox, but open source and, more importantly, actively maintained. https://zen-browser.app. - Source: Hacker News / 7 days ago

  • RendrKit: The Open-Source Alternative to Bannerbear
    Bannerbear is solid. You design a template, call their API, get an image back. They're doing around $40-50K MRR, plans start at $49/mo, and they've earned it. Placid and HTMLCSStoImage do similar things in slightly different ways. - Source: dev.to / 7 months ago
